ABSTRACT:
A rotary phase generator for generating 3 phase voltage is provided which can operate off of 230 or 460 volts A-C. Also provided is a rotary phase generator which has two groups of running capacitors for providing a stable voltage on the third phase at no load and light loads. In addition, a booster system is provided for a rotary phase generator to provide high starting torque to one or more of the motors operated on the rotary phase generator. A plurality of smaller rotary phase generators may be connected in parallel and started in time delay sequence to eliminate the heavy starting current when starting the system on one phase power.
